 Minor bugfix version. Plobary a good update.

 Fixes:
 Revised png_warning() to write its message on standard output by default
     when warning_fn is NULL. This was the behavior prior to
 libpng-1.2.9beta9.
   Fixed string vs pointer-to-string error in png_check_keyword().
   Added png_check_cHRM_fixed() in png.c and moved checking from pngget.c,
     pngrutil.c, and pngwrite.c, and eliminated floating point cHRM
 checking.
   Added check for zero-area RGB cHRM triangle in png_check_cHRM_fixed().
   In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant
     check for all-zero coordinates that is detected by the triangle check.
   Revised png_warning() to write its message on standard output by default
     when warning_fn is NULL.
 Corrected off-by-one error in bKGD validity check in png_write_bKGD()
     and in png_handle_bKGD().
   Revised bKGD validity check to use >= x instead of > x + 1
   Merged with png_debug from libpng-1.4.0 to remove newlines.
   Removed redundant check for key==NULL before calling png_check_keyword()
     to ensure that new_key gets initialized and removed extra warning
     (Arvan Pritchard).
   Added PNG_TRANSFORM_STRIP_FILLER_BEFORE and
     PNG_TRANSFORM_STRIP_FILLER_AFTER conditionals and deprecated
     PNG_TRANSFORM_STRIP_FILLER (Jim Barry).
